Attach this card to 1 of your Evolved Pokémon (excluding Pokémon-ex and Pokémon that has an owner in its name) in play. That Pokémon may use this card's attack instead of its own. At the end of your turn, discard Ancient Technical Machine [Ice].
Ice Generator アイスジェネレート
Discard all of your opponent's Trainer cards in play. If you do, prevent all effects, including damage, done to the Pokémon using this attack during your opponent's next turn.
The card's attack was later errata'd so that only effects from attacks were prevented, not all effects on the opponent's side of the field.
